Title: Refrigerant branching device
Inventor: UESUGI HIDESHI
IPC: F24F5/00
Filed: 1988-04-20
Abstract: PURPOSE:To simplify and facilitate the installation work when a number of indoor units varying in type and capacity are set in combination with one another by connecting the respective refrigerant branch pipes in series and employing pipes for the main pipe between adjacent refrigerant branch pipes with the same size. CONSTITUTION:A main pipe 4 which connects the outdoor unit 1 with the first refrigerant branch pipe 3 conforms in size with a connection pipe specified by an outdoor unit. A main pipe 5 which connects said branch pipe 3 with its following refrigerant branch pipe 3 conforms in size with the main pipe 4 being connected to the refrigerant branch pipe 3, therefore, its size become the same with that of the connection piping specified by the outdoor unit. After repeating the connection of a plurality of subsequent refrigerant branch pipes 3 an anchor refrigerant branch pipe 8 is connected only to an indoor unit 2, the size of the anchor pipe 8 conforms with that of a connection piping specified by an indoor unit. Thus the main pipes 4, 5, 6, 7 at all the sections except the anchor one are of the same size while the rest are all pipes specified by the indoor units in size so that, in the field work, there are no possibilities of wrong connection of pipes with regard to size.

IPC: G03B9/08
Filed: 1978-08-05
Abstract: PURPOSE: To discriminate the detaching of a lever and give warning and obviate the operation of a release circuit upon its detaching by oppositely providing switches to the iron core lever of the electromagnetic device.  
     CONSTITUTION: Switches So, Sc are oppositely provided to respective iron core levers 3 to enable the detaching of the levers 3 from the iron cores 1 to be discriminated. Now, when the terminal of a switch S 1  is changed over to b by pushing a release button, and if at least one of the switches So, Sc is held open, a transistor T 3  conducts through a buffer B 3  to cause an LED to light up, thereby giving warning. On the other hand, a transistor T 2  conducts through a buffer B 2  to supply current to the coil Lc for shutter closing release. In addition, a transistor T 5  is conducted through a buffer B 5  to supply current to the solenoid LD for down release of the mirror. In this way, when the levers 3 is held detached, warning as well as the closing release and the down release of the mirror are effected, whereby the film plane may be surely covered.

Title: Capacitor charge/discharge type ignitor
Inventor: MATSUZAKI KUNIO
IPC: F02P11/02
Filed: 1986-04-25
Abstract: PURPOSE:To prevent the reverse rotation due to erroneous ignition of 2-cycle engine by providing a switching means for controlling the conduction of main switching element and a switching means for cutting off a signal fed from a conduction detecting means for thyristor. CONSTITUTION:When the voltage withstandability of a thyristor 17 is deteriorated, a DC.DC converter boosts the voltage to produce a high voltage across an ignition coil 14 so as to cause discharge to a plug 15. Here, a voltage is produced across the thyristor 17 and a diode 18 to turn on a thyristor 34 so as to shortcircuit the power source for an oscillation circuit 7 thus turning off a switching transistor 6. If the voltage withstandability of the thyristor 17 is deteriorated not by an ignition signal, the thyristor 34 is continuously turned on until a switch 2 is opened so as to stop the oscillation of the DC.DC converter. In such a manner, the reverse rotation of 2-cycle engine due to erroneous ignition can be prevented.
